I love these socks. They fit nice and they look great. I have size 11 (US) feet, and these socks aren't too small. They come up to just below where my calf muscle starts, a few inches above the ankle. They've got a nice thickness too them, but aren't so thick they make your feet sweat or make it hard to fit in your shoes. They're just high-quality, and I'm sure they'd be good for a wide range of feet.
